The result of subtracting the second equation from the first is y = \frac{3}{4}

<u><em>Solution: </em></u>

Given system of equations are:

-3x + 2y = 7 ----- eqn 1

and -3x - 2y = 4 ---- eqn 2

We have to find the result of subtracting the second equation from the first

So we have to subtract second equation from the first

-3x - 2y = 4

-3x + 2y = 7

(-) -----------------

-4y = -3

4y = 3

y = \frac{3}{4}

Thus the result of subtracting the second equation from the first is y = \frac{3}{4}

Answer:

  There is no error

Step-by-step explanation:

While it is not necessary to guess an answer, because the answer can be calculated using the properties of equality, guessing is a legitimate solution method actually taught in (some) schools these days.*

The equation is properly written, data properly filled in, and the solution properly verified. There is no error.

_____

* What doesn't seem to be taught in US schools are methods of refining an incorrect guess. These are actually well-developed, and are legitimate ways to get to a good answer.

Use a definition, postulate, or theorem to find the value of x in the figure described.
Yuri [45]
The Definition of Linear Pair states that both ∠ABC and ∠CBD are equal to 180 degrees. In the question, this tells you that 
m∠ABC and m∠CBD = (3x − 6). 
So, you're equation should be (3x - 6) + (3x - 6) = 180. 
You would then solve to get 6x - 12 = 180, 6x = 192, x = 32
x=32, and we used the Linear Pair Theorem (C)

vlada-n [284]

Answer:

k = 3

Step-by-step explanation:

Expanding the first term, we find 1/x at 10(kx)²(1/x)³ = 10k²/x

Expanding the first term, we find 1/x at 8*1⁷(-2/x)¹ = -16/x

Then

10k² - 16 = 74

k = 3
